Mandala's strength is indeed not weak.
If it were outside, with Mandala's current strength, he could still manage to hold his own against some mid-stage All Things Realm experts for a while. If he can't win, retreating unscathed wouldn't be a difficult task.
But compared to Jing Yan, there was a significant gap.
How strong is Jing Yan? Before coming to Hongjun Heavenly Palace, Jing Yan effortlessly killed the Void Son Die Dong. Die Dong's combat power was not inferior to those ordinary All Things Realm Beings at all. Furthermore, Die Dong had a treasure with astonishing defensive capabilities obtained from the Void Divine Hall. Even so, Die Dong could not escape the fate of being slain by Jing Yan.
